SHOE-MAKERS neon LAST.

SPECZFICATIQN forming part of Letters Patent No. 310,723, dated January 13, 1885.

Application filed August 22, 1884. (No model.)

To aZZ whom it may concern:

Be it known that wadmuns ROBERTSON and J oHN F. TOBIN, subjects of the Queen of Great Britain, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Shoe-Makers Iron Repairing, Heeling,and Leveling Lasts; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of shoemakers repairing, heeling, and leveling lasts which comprise a metallic last and a supporting-standard; and its object is to provide a last of this class which will possess advantages in point of simplicity, inexpensiveness, strength and durability,and general efficiency.

In the drawings, Figure 1 is a perspective view of the improved last. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a de tail perspective view of the last proper. Fig. 4 is a detail perspective view of the base portion, illustratinga modification. Fig. 5 is a vertical sectional view illustrating another modification.

Corresponding parts in the figures are de noted by the same letters of reference.

Referring to the drawings, A designates the last proper, which may be of any suitable size or shape, and is constructed of castiron or other metal. In the under side of this last is provided an oblong hole or recess, a, which receives the corresponding top end, 12, of an upright standard, B. By reason of this improved construction embodying the oblong recess, the last is prevented from turning upon its supportingstandard, and is retained securely in position, and the strength and durability of parts is also enhanced. The oblong recess is of elliptical shape, as herein illustrated, by which arrangement a tight and secure connection is formed between the last and standard, whereby the former is rigidly and securely retained upon the latter, and against accidental lateral displacement. This improved construction also possesses advantages in point of strength and rigidity and economy of metal over the simple rectangular oblong recess heretofore employed, in which the standard does not correspond to or occupy the complete space of the recess.

0 designates a metallic base-plate,which embodies a central portion, a, formed with a re 'cess, a", in its top surface, 0. This recess is cylindrical and receives the corresponding bottom end, I)", of the standard, the latter being provided near its bottom end with a circumferential projection or shoulder, b", which rests upon the top surface, 0". By this arrangement the standard is adapted to rotate to be turned in or upon the base-plate to secure its convenient adjustment in relation to the workman. The base-plate rests upon the top of a post, 1), and is provided with lugs or ears 0, depending at its edge and embracing the top end of the post, suitable bolts, E, or other securing devices being passed through these cars and into the post to retain the base-plate securely in position.

The post D is designed to be fastened upon the floor, and to adapt the last to be operated by the workman in a standing position. By dispensing with the post and the ears upon the baseplate, the improved last is adapted for use at a low bench while in a sitting position, this form being shown in Fig. 4:, in which projections 0 are provided to fit the hollow of the foot of the workman. The standard is received by the last proper directly under the shank or hollow part of the last A, as shown, thereby equalizing the strain and securing great strength and durability. The last is provided with a hole or perforation, a in its heel portion, in which a withdrawing-hook is adapted to be inserted to facilitate the removal of boots and shoes from the last.

The operation and advantages of our invention will be readily understood by those skilled in the art to which it appertains.

The device is simple, durable, and inexpensive, and may be conveniently and readily adjusted.

In the modification illustrated in Fig. 5 is shown an improved form of base-plate and post, adapting the last to be conveniently operated when the workman is in astandingposition; In this construction the base-plate comprises two sections, F F, the former being secured upon the post D, and provided with a central hole or perforation, f, opening into a perforation, d, in the post, terminating in a slot, (F, at the bottom. The top section of the baseis cast or otherwise formed integral with the lower end of the standard, and is designed to fit and turn in the corresponding hole, f, it being provided with an annular projection or shoulder, f resting upon the top surface of the lower section, F. In this top section, F are provided two holes or slots,

10 f f*, through which a strap, G, extending over the top of the shoe when the latter is on the last, is adapted to pass down through the hollow post. The lower end of this strap engages alever, H, fulcrumed at one side the post, as illustrated at h, and adapted to engage a rack or ratchet, h, secured at the opposite side of the post. By this arrangement the strap may be tightened by pressure of the footupon the lever and the top section of the base. The standard and the strap can be readily turned to adapt them to the position of the workman.

lVe claim as our invention and desire to secure by Letters Patent 1. As an improvement in shoe-n1akers lasts, the combination of the last having the elliptical recess in its under side, the cylindrical standard having its top end conforming to the recess and received by the same, and provided with a cylindrical bottom end, 12 and withthe annular circumferential shoulder b above the same, and the base-plate having a central recess corresponding to and receiving the end of the standard, and provided with the ears at its edge by which it is secured in position, substantially as set forth..

2. The combination, in a shoe-makers last, of the last formed with the elliptical opening in its under side, the standard having a corresponding elliptical top end entirely filling said recess, and provided with a bottom portion formed with the annular shoulder and the slots f f the base-plate provided with the opening receiving the slotted bottom portion of the standard, and the retaining-strap passing through said slots, substantially as set forth.

In testimony whereof we affix our signatures in presence of two witnesses. I
